DTC P0340 DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Technical Service Bulletin(s) repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	VERIFY CMP SENSOR VOLTAGE Disconnect the CMP sensor connector. Connect voltmeter between CMP sensor terminals A and B (sensor-side). Inspect the voltage in AC range while cranking the engine. Is there any voltage?	Yes	Go to the next step.
3		No	Go to Step 10.
4	INSPECT POOR CONNECTION OF CMP SENSOR CONNECTOR Verify that the CMP sensor connector is connected securely. Is connector okay?	Yes	Go to next step.
4		No	Reconnect the connector, then go to Step 15.
5	INSPECT CMP CIRCUIT FOR SHORT TO POWER Turn the ignition switch off. Disconnect CMP sensor connector. Turn the ignition switch ON Engine OFF) Measure voltage between following terminal and body ground. CMP sensor connector terminal A (harness-side) CMP sensor connector terminal B (harness-side) Is any voltage reading?	Yes	Repair or replace suspected harness, then go to Step 15.
5		No	Go to next step.
6	INSPECT CMP CIRCUIT FOR SHORT TO GROUND Inspect continuity between following terminal and body ground: CMP sensor connector terminal A (harness-side) CMP sensor connector terminal B (harness-side) Is there any continuity?	Yes	Repair or replace suspected harness, then go to Step 15.
6		No	Go to next step.
7	INSPECT CMP CIRCUITS FOR SHORTS Inspect continuity between CMP sensor connector terminals A and B (harness-side). Is there any continuity?	Yes	Repair or replace suspected harness, then go to Step 15.
7		No	Go to next step.
8	INSPECT POOR CONNECTION OF PCM CONNECTOR Disconnect PCM connector. Inspect for poor connection (damaged, pulled-out terminals, corrosion, etc.). Is there any malfunction?	Yes	Repair terminal, then go to Step 15.
8		No	Go to next step.
9	INSPECT CMP CIRCUIT FOR OPEN CIRCUIT Inspect continuity between following circuits: CMP sensor terminal A (harness-side) and PCM terminal 2V (harness-side) CMP sensor terminal B (harness-side) and PCM terminal 2U (harness-side) Is there continuity?	Yes	Go to Step 11.
9		No	Repair or replace suspected harness, then go to Step 15.
10	INSPECT CMP SENSOR Turn the ignition switch off. Perform CMP sensor inspection. (See CAMSHAFT POSITION (CMP) SENSOR INSPECTION .) Is CMP sensor normal?	Yes	Go to Step 15.
10		No	Replace CMP sensor and go to step 15.
11	VERIFY CKP SENSOR INSTALLATION Verify CKP sensor installation. (See CRANKSHAFT POSITION (CKP) SENSOR REMOVAL/INSTALLATION .) Is CKP sensor installed correctly?	Yes	Go to next step.
11		No	Reinstall CKP sensor and go to Step 15.
12	VERIFY VALVE TIMING MECHANISM INSTALLATION Verify valve timing mechanism installation for following parts: Timing chain misinstallation Loose camshaft sprocket lock bolt Loose crankshaft pulley lock bolt Is valve timing mechanism installed correctly?	Yes	L3: Go to the next step LF: Go to Step 15.
12		No	Reinstall following parts and go to Step 15. Timing chain Camshaft sprocket Camshaft pulley
13	INSPECT STOPPER PIN MECHANISM Remove timing chain. Inspect stopper pin. (See VARIABLE VALVE TIMING ACTUATOR INSPECTION [L3] .) Is stopper pin mechanism normal?	Yes	Go to next step.
13		No	Replace variable valve timing actuator, then go to Step 15.
14	INSPECT ROTOR POSITION Remove variable valve timing actuator. (See VARIABLE VALVE TIMING ACTUATOR REMOVAL/INSTALLATION [L3] .) Is rotor position at maximum valve timing retard?	Yes	VARIABLE VALVE TIMING MECHANISM IS NORMAL NOTE: This DTC detected by intermittent concern. Intermittent concern might be removed by cleaning mode of variable valve timing control function. Go to next step.
14		No	Replace variable valve timing actuator, then go to next step.
15	VERIFY TROUBLESHOOTING OF DTC P0340 COMPLETED Make sure to reconnect all disconnected connectors. Turn the ignition switch ON (Engine OFF). Clear DTC from PCM memory using WDS or equivalent. Start engine. Access MAF PID using WDS or equivalent. NOTE: MAF PID should indicate 1.95 g/s {0.25 lb/min.} or above during this test Is same DTC present?	Yes	Replace PCM, then go to next step. (See PCM REMOVAL/INSTALLATION .)
15		No	Go to next step.
16	VERIFY AFTER REPAIR PROCEDURE Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE ) Is there any DTC present?	Yes	Go to applicable DTC troubleshooting. (See DTC TABLE )
16		No	Troubleshooting completed.
